Just wondering if anyone knows if the ITR intake valves will go straight into a B16a2 head, does anything need to be done to the head to prep it for the install eg new valve guides, I was told it may need new steam seels what ever that means, what are the differences in dimensions of the 2 intake valves(ITR vs b16a2)?

 

dimensions are the same, just the ITR valves use a steeper seat angle.
This also means you will need the seats cut in order for them to seal properly.
